TO ALL WHOM IT MAY CONCERN: i

Be it known that I, M. s Rumours, of the parish of Ascension, in theState of Louisiana, have invented a certain new, useful, and improvedMachine for Filtering Liquids; and I do hereby declare the following tobe a full, clear, and exact description of the some, reference being badto theanuexed drawing, making a part of this specification.

Before I proceed to indicate the nstureof my'invention, or to describeits mode of operation, a few introductory remarks as to the causes thatgive it value andimportance will not be out of place.

It is familiar knowledge to every intelligent mind that the water wedrink and use in cookery has a decided influence for good or evil uponour, general health. If that water be pure, the influence is fnvorable,but a contrary effect is rearlyalways produced if it be impure. The.impurity may proceed from mechanical vices altogether, or from such asare wholly chemical, or it may beproduced by both these vices combined.f The former are usually visible, if not in individual form, ltleustcollectively, as when the color or density of the water is changed bytheir presence and incorporation in it. The latter are for the most partheld in solution, and often flail even to discolor the water, or inany-other manner discernihly to afl'ect it, excepting only through theeflects that are produced by its use. Very much of the water that isused in large cities andtowns contains b th mechanical and chemicalimpurities, and needs to be freed of the slams before it can beusedfwithout risk of deleterious ofi'ect upon the health of the people.-

lspocially is this the case in the city of New Orleans, wherein theturbid water fromfthe Mississippi river, or the foetid infusoria-la'lenrain-water of the cisterns, constitutes the whole supply, and which,therefore, must be made to subserre every purpose whstsoevor. To e veryconsiderable extent the aims thing obtains along the whole course of theMississippi river, as well as in its great vvsterbeds, and hencetheprevaloncc in these localities, particularly at certain sessons ofthe year, of at rest variety of disturbances or disorders of the stomachor barrels, and the consequent serious diseases that are incidentthereto or follow'the'rofrom.

Now, although a mere filtration, however periect and searching it mayhe, does not necessarily rid water of its chemical impregnations, it iscertain that all merely mechanical impurities are eliminated thereby,and that, as s geueralthing, the more active and potential chemicalvices ere suliiciently removed or reduced as to render them practicallyharmless. Hence it follows that water that has been well filteredissulliciently pure for generol purposes of health, and that's filteringmschino that can thus affect the waterjhat is used by the dense massesof large cities, in n short space of time, and at a trifling cost ofmoney, becomes of incalculablc value and importance to a city like thatof New Orleans. My invention fulfils all these conditions, and goes farbeyond them in its adaptations to other spheres of usefulness, in someinstances of narrower scope, in others of for wider influence andeffect. And it consists of an improvement upon or an addition. to theordinary ceutrifugalsjhet are almost universally used in connection withthe manufacture of sugar from cone-juice.

I do not alter said centriiogulsin the slightest particular, exceptingthat I may sometimes make theui smaller and sometimes larger, and myinvention consists simply in inserting, within the revolving perforateddrum therein, n wall of felt, or other equivalent substance, which,impinging closely upon'the perforated perimeter of said drum'interiorly, takes up the impurities ssthe wsteris forced through it bythe centrifugal force that is brought into action by the revolution ofthe drum. Felt, and several other like substances, will'answeir v yurpose where the water is to be freed of mechanical ingredients, butwhere there has been an infusion of deleterious chemical elements, andantiseptic eliects are requisite to complete the process ofpurification, oi

carbonaceous wall may be substituted for it, or the wall may be of anyother substance that will better-produce the desired result.

But my invention will be better understood by referring to the drawings,which, at-

.Figure 1, represent the ordinary perforated revolving drum at asugar-centrifugal, and at Figure 2 a sectional view of the some with myinvention attached thereto.

I have not considered it requisite to show the whole of a centrifugal,because the constructionof the lame is well known to all persons at allacquainted with the making of sugar, and because, furthermore, my'invem'tiou refers exclusively to the-revolving perforated drum,-.vghich isshown; but it willbeunderstoodthat, although not represented ordescribed, I propose to use the whole apparatus, in order to prevent theescape of the filtered water, andsto control its.subsequentdistribution.

On the drawings, A represents the perforated perimeter. of thedrutn, andB my inner wall, 'of felt or other substance, and these parts-exhibitthe whole of my invention.

The operation is as follows, to wit: Water is poured into the drum atthe opening 0, ins continuous stream, I

whilst the drum is rotated rapidly, say at the rate of fifteen hundredor more revolutions a n inute, and by the centrifugal power that isdeveloped, it (the water) is forced through the felt or other material,whatever the same maybe, and through the minute perforations in the;perimeter of the drum, in a pure state, whilst the impurities remain inthe felt. The water escapes in the form of spray, and is dashed againstthe concentric wall of thecerltrifugal, that is not shown on thedrawings, and then falls to the bottom of the machine, whence it iscarried by pipes wherever it is wanted. v

Two or three machines of double the size of the ordinary sugar-housecentrifugal would, if kept in action constantly, at a rapid rate ofrevolution, filter water onoughto supply the entire need of thepopulationof New Orleans. v

Small machines could be put on board every steamboat on the Mississippiriver, and on every plantationon its banks, and thus secure pure waterfor the thousands whom-e now obliged todrinl: or otherwise ns the :muddywater as it is drawn from the'great river, to the great prejudioeoftheir health.

Sea-going vessels could be provided in the same way, and so, at properintervals, nzight be purified th'mhi k. ening water in the tanks, to theinfinite relief and comfort of every person on board the-same.

But I need not specify the manifold uses to which my invention may beapplied, wherever steam or horse or hand or any other power may besoouredto operate ityzior yet the vast advantage it possessesover everyfiltering-machine heretofore devised, in its capacity-for accomplishinggreat results,- for boththese points" are so plainly obvious, on theslightest reflection, that it would be a work of supererog'ation were Ito attempt the task.

Whenever the inner wall of felt or other substance needs to be cleanedfrom an accumulation of matters that have been taken from the water byit, it can be withdrawn and washed, and'then put back again with greatease and dispatch. Or, a wall of one substance may be substituted foranother, at any time, to suitvarying' conditions of the water to befiltered, with equal rapidity and facility. a

Having thus described my invention, what I claini, and desire to secureby Letters Patent, is-

The process of filtering water, by passing, it through a-vessel,constructed and operating substantially as described, whereby it issubjected to the notion of centrifugal force, and a more rapidfiltration is. effected, as set forth.
